RPM rsync Distributor¶

Purpose:¶

The RPM rsync distributor publishes RPM content to a remote server. The distributor uses rsync over ssh to perform the file transfer.

Configuration¶

Pulp’s SELinux policy includes a pulp_manage_rsync boolean. When enabled, the pulp_manage_rsync boolean allows Pulp to use rsync and make ssh connections. The boolean is disabled by default. The RPM Rsync distributor will fail to publish with SELinux Enforcing unless the boolean is enabled. To enable it, you can do this:

$ sudo setsebool -P pulp_manage_rsync on

Here’s an example of rpm_rsync_distributor configuration:

{
    "distributor_id": "my_rpm_rsync_distributor",
    "distributor_type_id": "rpm_rsync_distributor",
    "distributor_config": {
        "remote": {
            "auth_type": "publickey",
            "ssh_user": "foo",
            "ssh_identity_file": "/home/user/.ssh/id_rsa",
            "host": "192.168.121.1",
            "root": "/home/foo/pulp_root_dir"
        },
        "predistributor_id": "yum_distributor"
    }
}

predistributor_id: The id of the yum_distributor associated with the same repository. The publish history of this yum_distributor determines if the publish will be incremental.

The distributor_config contains a remote section made up of the following settings:

ssh_user

ssh user for remote server

ssh_identity_file

Absolute path to the private key that will be used as identity file for ssh. The key must be owned by user apache and must not be readable by other users. If the POSIX are too loose, the SSH application will refuse to use the key. Additionally, if SELinux is Enforcing, Pulp requires the key to be labeled with the httpd_sys_content_t SELinux context. This can be applied to the file with:

$ sudo chcon -t httpd_sys_content_t  /path/to/ssh_identity_file

host

The hostname of the remote server.

root

Absolute path to the remote root directory where all the data (content and published content) lives. Remote equivalent to /var/lib/pulp. The repository’s relative url is appended to the root to determine the location of published repository.

Optional configuration¶

force_full: If true, the rsync distributor will publish all of the content of the repository. If false (default), the publish is incremental when the predistributor’s last publish was incremental. This value does not affect the skip_repodata and content_units_only configs.
content_units_only: If true, the distributor will publish content units only (e.g. /var/lib/pulp/content). The symlinks of a published repository will not be rsynced.
skip_repodata: If true, repodata will be omitted from the publish.
delete: If true, --delete is appended to the rsync command for symlinks and repodata so that any old files no longer present in the local published directory are removed from the remote server.
remote_units_path: The relative path from the root where unit files should live. Defaults to content/units.
rsync_extra_args: list of strings that can be used to extend default arguments used for rsync call.
